This cable is no in Figure 7.connected with a controlling switch 31 which is mounted upon the handle28 and is wound upon a reel 32 so as to permit the mower to be movedover a relatively large area. Suitable connection 33 is provided-betweenthe reel and the motor 16.

If desired, the mower may be operated through the medium of an internalcombustion engine as shown at 34 in Figures 7 and 8 of the drawings.This engine is mounted in a saddle or frame 35 which rises from "thehousing 15 and the power shaft of the engine drives a verticallydisposed shaft 36 through the medium of gears 37. The arms 20 and 23 aremounted upon this shaft 36. I

The fiy wheel of the engine is indicated at 38 while the carburetor isshown at 39 and fuel from this carburetor is supplied from a tank 40which is mounted'upon ,the handle 28, a fuel supply pipe 41 beingprovided for this purpose.

A suitable battery is contained within a battery box 42 which is alsomounted upon the handle and current is supplied to the ignition device43 of the engine through a cable 44. A

' switch 45 mounted upon the handle 28 controls the ignition.

In the first described form of the invention where current for theoperation of the mower is supplied through a cable 30, means areprovided for keeping the cable out of the way of the wheels. This armwhich is indicated at 46 is pivotally and adjustably-secured to thehandle 28 by means of a bolt 47, so that it may be swung laterally toeither side of the handle. The outer end of this arm carries a springclip 48 which is adapted to yieldingly grip the cable 30. The cable maythus be held in position at either side of the handle 28 to prevententanglement with the wheels of the mower and to clear shrubs, trees andother obstructions.

The invention is susceptible of various changes in its form, proportionsand minor details of construction and the right is herein reserved tomake such changes as properly fall within the scope of the appendedclaims.

The invention claimed is; 1. A power operated lawn mower comprisingaportable carriage, a power source carried by the carriage, a shaftdriven by the power source and depending therefrom under the carriage,oppositely disposed and downwardly curved arms having the inner endsthereof adjustably secured to the shaft, cutting blades secured to thearms adjacent the free ends thereof and having curved cutting edgesdisposed laterally of the arms, and oppositely disposed fan bladesadjustably secured to the shaft above the cutting blades to create asuction to the uncut grass to draw the grass into the path of rotationof the cutting blades.

2. A power operated lawn mower comprising a wheeled frame, a housingcarried by said frame and having substantially imperforate top, sidesand ends and an open bottom, said housing defining a confined air space,a vertical shaft extending down into said space, a motor connected tosaid shaft for rotating the same, blade type cutters having lateralcutting edges andifcarried by said shaft and disposed to rotate in asubstantially horizontal path, and means rotated with said shaft andlocated within said housing for creating currents of air in said housingand upwardly through the path of rotation of said cutters to draw thegrass up into the field of I action of said cutters.

the ground, a vertical shaft extending down into said air space, a motorconnected to said shaft for rotating the same, a blade type cutterhaving a lateral cutting edge carried by said shaft and disposed torotate in a substantially horizontal path adjacent the bottom opening ofthe housing, and a fan blade driven by said shaft and rotatable withsaid cutter and having an air defiecting surface for advancing airupwardly from the ground into the region of the cutter through thebottom opening of the housing and past the path of movement of thecutter whereby to draw grassupwardly into the field of action of thecutter.

4. A mower of the character described comprising a mobile frame having ahousing defining a confined air space and open at its bottom adjacentthe ground, a blade type cutter supported for rotation in a horizontalpath adjacent the bottom opening of the housing, means for rotating saidcutter, and means rotatable with said cutter and having air deflectingsurfaces for advancing air upwardly from the ground in the region of thecutter through the bottom opening of the housing and past the pathofmovement of said cutter whereby to draw the grass upwardly and into thefield of action of the cutter.

5. A mower of the character described comprising a mobile frame having ahousing defining a confined air space and open at its bottom adjacentthe ground, a blade type cutter supported for rotation in a horizontalpath adjacent the bottom opening of the housing, means for rotating saidcutter, a fan blade disposed adjacent the bottom opening of the housingand rotatable with 110 said cutter about a vertical axis for advancingair upwardly from the ground in the region of the cutter through thebottom opening of the housing and past the path of movement of saidcutter whereby to draw the grass upwardly and into the field of actionof the cutter.

6. A power operated lawn mower comprising a mobile carriage having ahousing defining a confined air space and open at its bottom adjacentthe ground, a power source carried by the carriage, a shaft driven bythe power source and depending therefrom into the housing, ahorizontally disposed cutting blade secured to the shaft and rotatedthereby, said cutting blade having a cutting edge sloping laterallywhereby to eifect the cutting of the grass with a sweeping action, andmeans rotatable with said cutting blade and having air deflectingsurfaces for advancing air upwardly from the ground in the region of thecutting blade and past the path of mov'ement thereof whereby to draw thegrass upwardly and into the field of action of the cutter.

7.A mower of the character described comprising a mobile frame, ahousing thereon defining an air space and openat its bottom adjacent theground, a vertical shaft extending down into said space, a motorconnected to said shaft for rotating the same, a horizontallydisposeddouble bladed cutter secured to said shaft and rotated thereby adjacentthe bottom opening of the housing, said cutter having cutting edgessloping laterally whereby to effect cutting of the grass with a sweepingaction, and means rotatable with said cutter for advancing air upwardlyfrom the ground in the region of the cutter through the bottom openingof the housing and past the path of movement of said cutter whereby todraw gras'supwardly and into the field of action of the cutter.
